To all whom it may Gomera Be itiknown that Dr. KRL SCHEINER, a citizen of the United States, resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements -in ll/.lotor-Oycles, of which the following is a specification.

This invention relates to improvements in frame constructionfor Vehicles and has'as its special` object the provision of means whereby the framelof an ordinary motor cycle-may be transformed into that of a goods or passenger carrier by the additons of a limited number of simpleparts and without change in the main elements, such as wheels, motor, driving gear, steering means and'seat of a motor cycle asnow made. A further object is to provide' a complete vehicle frame whereby the same ,purposes are -attainedV These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this specification, and in which,

VFigure 1 is a side elevational view, showing a complete vehicle in accordance with the invention.

Fig. 2 is a topplan view thereof.

Fig. 3 is a fragmental plan view, drawn to an enlarged scale, the seat being removed.

Fig. 4 is a Vertical sectional view taken substantially on line 4-4 of Fig.` 3.

Fig. 5 is a fragmental top plan view showing' a modified form of the frame.v

F ig. 6 is a side elevational and Vertical sectional view, the section being taken on line 0-6 of Fig. 5, and

Fig. 7 is a transverse sectional view taken on line 7-7 of Fig. 6. y i

In carrying out the invention use may be made of the frame of an ordinary 1motor cycle, provided with a front wheel 10 and rear wheel 12, arranged uponlan laxle`14. The front wheel operates between forks 15, steered by the handle bars 16, and secured to the forks, at their upper ends, is a standard fitting 18, in the upper opening of which is engaged 'a bar 19, a strut' 20, connecting with the lower opening of the fitting, while a horizontal bar 21, conneets between the fitting 22 on the strut and a seat support 24 in which is engaged the seat 25 and also has connected the rear end ofV the bar 19, formil'ig ineifect a 'variety of the well known diamond frame.

Extending downward from the seat`` support 24 is a bar 26 formed with a bracket 27 to which isiengaged the gear ucasing 28 of the motorI 29. Alpair of oppositely disposed pedals V30, have their shaft pass through the casing and are connected `with the gearing so that the vehiclecanbe propelled by foot power' when Vdesired.

j Angularly disposecl bars 32, are engaged in the rear yokes 33 in their upper openings, while in the lower openings are other tubular bars 134, extending to the engine frame, which is` comprised of across bar 35, engaged with the bracket 27, and `yparallel bars 36 which connect with a cross block in which the bars 34 are fixed. I I

The improvement consists in the application of Aparts which serve to lengthen and wden the'frame ``so that a' container 40, of considerablemagnitude, or passenger seats may be readily carried' vand operated as a part .of the vehicle.

To this purpose a pairof `wheels 12 are secured to the axle 14, on which is mounted a pair of semi-elliptio springs` 41 by brackets 48, the'springs being engaged by pivoted links`42 With ,end fittings 43, secui'ed upon horizontaltubular bars 44, having engaged between them cross bars 45, forming a rectang'ular frame, at the front of which the extending ends 46 of the side bars 44 are bent toward each other and pivotally connected ,by a bolt 49 to the seat supportl 24. a In the spring brackets 48 are also engaged the' endsiof angularly disposed tubular bars 50, oonnected'attiheir converging front ends by a Y fitting 51, in the straight front opening of which is secured `a"tubular bar A52, internally screw threaded at` its outerend to receive a threaded stem 58,' formed with a cup 54, containing a spherical element `55, freely movable'therein and engageddby a stem 56 to a bracket 60 securedto the block 37 of the engine sup orting frame. W

Extending from t le `fittings 43 and engaging between the side bars 44 and braces 45, are the bars 62 carrying bolts 63``` freely slidable in the slots 35, of the yokes which formerly contained the rear aXle, thus providing an extension frame upon which the car or container 40 may be mounted and which can be used with the main frame of the' motor cycle without material change ther'ern; thel drrve'hai'n G'4t'lfeii1'g'V lengthened to convey motion to the drving spro'cket Due to the adjnstability'ofthe'barjiand"i" flexibility of its onter connection with the Sphere 55, the entire frame is rendefei'dn" limitedly flexible, While wear and lost mo-V tion'ia 'ibe'talefi flip' 'by ustmnt' of" thel In the modifica-ton shown in Fig's. 5 and 7. ,inelnsiye vthe, frame elements are arranged to ohtai'g'i' a i .sovthat'ishould tl1e,.Ve-hiclebe ratediiponan.nnevensurfa ,and one." therear Wheels lrased above v. ichinvistingf'movement`l`` is not transinittedto the seat' or frontportion of thefranie;This 'is'f accomplihed inthe i .i inai1"n(-:r, :,LQV w All' I) le-VPOFis-xngaged byitheb'olt 49 fi.
